IMPROVEMENT IN MACHINES FOR PUNCHING METAL LATHS.

Specification forming part of Letters Patent No. 176,5 ll, dated April 25, 1876; application filed March 2.3, 1876.

To all whom it may concern:

Be it known that we, LE ROY CARPENTER, vto'ron KAUFFMAN, and EASON WHITE, of Beardstown, C ass county, Illinois, have invented a new and Improved Machine for Preparing Metal Lathing, of which the following is a specification:

Our invention consists of a couple of metal rolls, having punches for making slits for the plaster; also, punches for making the nailholes by which to fasten the sheets on the studs, and one having a cutter for trimming the sheets, which said rolls are geared together, and provided with a hand-crank or other means for turning them, making a simple and efficient contrivance for preparing metal sheets for plastering.

Figure 1 is a longitudinal elevation of our improved machine taken on line or as. Fig. 2 is a plan "iew, and Fig. 3 is a section, of the metal lathing, such as the machine is used to prepare with a coat of plaster applied.

Similar letters of reference indicate corresponding parts.

A is the upper roll, and B the lower one, of a'pair arranged with a suitable table; (3, on which are guides D for running the sheets between them, and which are geared together and provided with driving-gear F. The rolls are made hollow, and the lower one has dies G H, for which the other one has corresponding punches I J, the former being to punch the holes K for the plaster, and the latter to punch the holes L for the nails by which the sheets are attached to the studs. M represents a cutter on the upper roll for trimming the sheets at the same time they are punched. N represents the perforated sheet, and O the plaster applied to it as when arranged in the building. 4

Having thus described our invention, we claim as new and desire to secure by Letters Patent The combination of roll A, having the punches I J and the cutter M, with the roll B, having the dies G H, said rolls being geared together and arranged in connection with table 0 and guide D, substantially as specified.
